Abstract
"APRIMORADA EFICIêNCIA DE FILTRAçãO". Uma composição de revestimento se enxerta quimicamente a celulose ou a sintéticos, e o produto resultante serve como um filtro em um sistema de filtragem o qual mantém o liquido ou o gás filtrado limpo mediante a remoção de fuligem, de sólidos, de líquidos e de outros contaminantes, maximizando desse modo à vida útil dos equipamentos ou dos motores. O revestimento é desenvolvido usando enxertia química que envolve o uso de monómeros, pré-polímeros, catalisadores, um sistema iniciador de enxerto e/ou outros ingredientes. o revestimento resultante é usado para tratar algodão, outros materiais de celulose, materiais sintéticos e combinações deles provenientes, e provê quanto à polimerização por enxerto, formando desse modo um filme polimérico o qual é quimicamente unido à fibra de algodão, a fibras outras de celulose, a sintéticos ou a combinações delas provenientes com excelente aderência, conferindo desse modo todas as propriedades desejadas à fibra em termos de aumentada eficiência de filtração."IMPROVED FILTERING EFFICIENCY". A coating composition chemically grafts to cellulose or synthetics, and the resulting product serves as a filter in a filtration system which keeps the filtered liquid or gas clean by removing soot, solids, liquids and other materials. contaminants, thereby maximizing the life of equipment or motors. The coating is developed using chemical grafting involving the use of monomers, prepolymers, catalysts, a graft initiator system and / or other ingredients. The resulting coating is used to treat cotton, other cellulose materials, synthetic materials and combinations thereof, and provides for graft polymerization, thereby forming a polymeric film which is chemically bonded to cotton fiber, other cellulose fibers. Synthetics or combinations thereof come with excellent adhesion, thereby conferring all the desired properties on the fiber in terms of increased filtration efficiency.
